In User-Interface Prototyping, the user interface is developed quickly to explore the user-interface design and the system’s requirements.
Sometimes a special-purpose prototyping language is used; other times prototyping is done in the target programming language. User-interface prototypes are either thrown away or evolve into the final product.
Making the right choice about whether to evolve the prototype or throw away is one key to success. Other keys to success include involving end-users appropriately, keeping initial prototype implementations as simple as possible and using experienced developers.
Potential reduction from nominal schedule: Good
Improvement in progress visibility: Fair
Effect on schedule risk: Decreased Risk
Chance of first-time success: Excellent
Chance of long-term success: Excellent
- Prototype polishing
- Risks of Evolutionary Prototyping or Throwaway Prototyping, depending on whether the user-interface prototype is evolved or thrown away
